`G_DBUS_ERROR_FAILED`

  A generic error; “something went wrong” - see the error message for more.

  - Value: `0`
  - Available since: 2.26

  - Value: `3`
  - Available since: 2.26
`G_DBUS_ERROR_NO_REPLY`

  No reply to a message expecting one, usually means a timeout occurred.

  - Value: `4`
  - Available since: 2.26
`G_DBUS_ERROR_IO_ERROR`

  Something went wrong reading or writing to a socket, for example.

  - Value: `5`

#### Type functions

###### g_dbus_error_encode_gerror

Creates a D-Bus error name to use for `error`. If `error` matches a registered error (cf. g_dbus_error_register_error()), the corresponding D-Bus error name will be returned.

since: 2.26

###### g_dbus_error_get_remote_error

Gets the D-Bus error name used for `error`, if any.

since: 2.26

###### g_dbus_error_is_remote_error

Checks if `error` represents an error received via D-Bus from a remote peer. If so, use `g_dbus_error_get_remote_error()` to get the name of the error.

since: 2.26

###### g_dbus_error_new_for_dbus_error

Creates a `GError` based on the contents of `dbus_error_name` and `dbus_error_message`.

since: 2.26

###### g_dbus_error_quark

No description available.

###### g_dbus_error_register_error

Creates an association to map between `dbus_error_name` and `GErrors` specified by `error_domain` and `error_code`.

since: 2.26

###### g_dbus_error_register_error_domain

Helper function for associating a `GError` error domain with D-Bus error names.

since: 2.26

###### g_dbus_error_set_dbus_error

Does nothing if `error` is `NULL`. Otherwise sets `*error` to a new `GError` created with `g_dbus_error_new_for_dbus_error()` with `dbus_error_message` prepend with `format` (unless `NULL`).

since: 2.26

###### g_dbus_error_set_dbus_error_valist

Like `g_dbus_error_set_dbus_error()` but intended for language bindings.

since: 2.26

###### g_dbus_error_strip_remote_error

Looks for extra information in the error message used to recover the D-Bus error name and strips it if found. If stripped, the message field in `error` will correspond exactly to what was received on the wire.

since: 2.26

###### g_dbus_error_unregister_error

Destroys an association previously set up with g_dbus_error_register_error().

since: 2.26
